How to organize WebRTC between local networks?

Question

Node.js

Greetings, the essence of the matter is this - we have two local networks, a server is connected to these two local networks.
We need to organize video calls via WebRTC, because they are P2P, then people who are in the same local network can communicate through it.
How can we organize so that people can connect to another local network, of course, through our server? Is there any server for this, which organizes communication between subscribers in two ways - WebRTC or Streaming through the server? For if you do two options, just streaming and WebRTC - Labor-intensive, preferably everything based on it

Answer 1

1. Set up a signaling server to help peers find each other.
Example: https://simplewebrtc.com/
2. You can try to use serverless-webrtc
3. If your local networks are separated at the routing level, and the only point of contact between them is your server that you mentioned, then I would try to raise on this proxy server, which would serve as a pipe for transferring data between networks. Confuses only whether the server can withstand such a load.

Answer 2

Will the TURN server help in this situation?

Answer 3

A WebRTC server that proxies traffic will help here, for example this one . Works, as far as I know, even under VPN. The truth will not be p2p.
The TURN server will most likely help, only it needs to be cleverly configured.
